I wouldn't think so.  MTB brakes would stop you far quicker than a truck, 
especially an articulated one.  Truckers have to be very aware of their 
stopping distances and they risk jackknifing if they brake too hard.  But the 
closer you follow the better your reflexes need to be :)

I drafted for the first time just the other day, but I was only drafting behind 
another couple of road cyclists.  It's amazing how much energy you save and 
goes a long way towards explaining why I can never drop people who sit on my 
wheel when I'm out on a solo training ride.

Just start pedaling with a weird cadence, speeding up and slowing down so that 
they can't be so close without risking hitting you.  Or, probably safer, you 
could try swerving a couple of feet to the side before sprinting. That way they 
suddenly go from being in the draft and not having to pedal so hard, to getting 
a bunch of wind slowing them down, while you are already pushing hard to speed 
up.

 nice story. thanks for sharing. when we do group rides here, it is
 usually about six to eight people and within the 20th km we are all
 spread out far and wide so never done something like that... :)

This was an organized ride, with rest stops, sag wagons etc.

According to the Versus Tour-de-France commentators (who have
ridden in the tour, so presumably know something about it)
you use something like 30% less energy when you are drafting.

I suspect it's even more than that, depending on what you're drafting.  When I 
was training for the DC one day, I expected to miss my afternoon class, when 
one of my classmates rode by on her moped.  I was able to draft her at 
something like 25 MPH when my normal cruising speed was much closer to 15.

occasioned by drew's OT running post...

did a century ride on the cycle yesterday (about 134 km in a little more
than six hours on an MTB on a regular highway :)). the highlight was
drafting for about 10km behind a petrol tanker truck at about 35km/h.
have seen guys doing it behind faster-moving trucks, but since this was
my first time, chose a not-so-fast truck to draft behind. quite a heady

My father-in-law told me once of an incident that happened to him  
he was bus driver back in the days when town buses had the open platform 
at the rear where passengers could jump on and off.   He was bringing a 
bus back to the main depot from one of the smaller ones, as he was not 
in service he was travelling about 40 mph along a long straight road, he 
put the indicator on and braked to turn into the depot. There was a 
horrible clatter and cyclist and his bike were suddenly right up the 
front of the bus next to him in the driver's seat.  The poor chap had 
been drafting him but couldn't get out of the way when he braked and 
'used' the open platform at the rear to get on-board.  He apparently 
'only' broke his leg and got cuts and bruises.

I've never drafted a truck, but back in college when I did longer rides, I did 
a lot of wheelsucking.

Perhaps the best one was the time I rode the Davis Double Century solo.  My 
goal was to be back by dark, and when I was about 50 miles out it looked like 
there was no way I was going to make it. Then a tandem went past like I was 
standing still, so I asked if I could draft. They said no problem and I 
jumped in behind them.  Within a couple of miles the draft line had grown to 
about 30 bikes.

The reason the tandem was running so late was  that at the start of the ride 
there are all these huge packs and draft lines of 50, maybe 150 bikes. Every 
year, someone will see a cop car at one of the farm road intersections and 
before they notice the cop is controlling traffic will slam on their brakes to 
keep from running the stop sign that they were going to blow off.  It is not a 
good thing when someone suddenly slams on their brakes in the middle of a draft 
line.

On another ride (I think it was the metric double that I did without training, 
on a bike without a front derailleur, I was chatting up a girl I had caught up 
with and she said she needed to back off the pace.  I said she could draft me

our roads being what they are especially during /immediately after
monsoons, there is also the additional problem of (sometimes
huge) potholes since one can't see the road ahead. i guess most
cyclists who draft know what is involved and like i told Bob, i have
been cycling for almost two years now and just wanted to see what it
was like... :)
